Given numbers are 345, 777, 157, 909

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(345, 777) = 89355

GCD(345, 777) = ( 345 x 777 ) / 89355

= 345 / 777

= 345

Step2:

LCM(3, 157) = 471

GCD(3, 157) = ( 3 x 157 ) / 471

= 3 / 157

= 3

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 345, 777, 157, 909 is 1
